MONROE L. BATTELL, OF NEV YORK, N. Y.

IMPROVEMENT IN QUARTZ-CRUSHERS.

Specification forming part of Letters Patent No. 59,165. dated October 30, 1866.

To all whom it may concern:

Be it known that I, MONROE L. BATTELL, of the city, county, and State of New York,

have invented a new and Improved Ore-Gruslr ing Machine; and I do hereby declare the following to be a full and exact description thereof, reference being had to the accompanying drawings, forming a part of this specification, in which Similar letters indicate like parts in all of the figures.

The nature of my invention consists in combnnng in one machine two distinct pairs of crushing-jaws, operated by a single intermediate driving-shaft in such a manner as that the jaws shall be closed alternately by each revolution of the shaft, so that the ore partially crushed by the first or upper jaws may be finally and finely pulverized by the second, to which it is conducted by any suitable device.

My improved crushing and pulverizing machine is constructed of stout upright frames A A B B, secured in a parallel position upon a suitable bed-plate or platform, (3, and braced by transverse beams D D.

Upon the frames A A are secured journalboxcs E E to receive the journals of a strong driving-shaft, F, which communicates motion to the operative parts of the machine. At the front end of the frames I place a stationary counter-plate, H, extending transversely between the uprights B B, and resting firmly in an oblique position upon and against supportin g-cleats G G fastened against said uprights, as illustrated in Fig. 1, which incline outwardly from the shaft F.

The plate H is secured to the supportingstrips by means of bolts and nuts which allow itsadjustment. This adjustment is obtained by inserting or withdrawing narrow strips a between the plate and the cleats. Immediately opposite the counter-plate H, and at an angle inclining therefrom, I pivot a corresponding crushing and grinding plate, K, upon short arms I) b hinged to an axle, 0, extending across from frame to frame, A A. The center of motion of this plate is, by means of these arms, set back several inches from its loweredge, so that the motion of its face, when the plate is rocked upon its hinged arms, is-compound, viz., in addition to the vibratory or re ciprocating movement to and from the oppo site stationary counter-plate H, it has a raking sweeping movement in an are described from the axle as its center.

The reciprocating or rocking movement of the plate K upon its hinges at the axlec is obtained by means of two strong shackle-bars, M M, pivoted at one end to the upper free end of the plate K and at the other upon eccentric journals formed on the driving-shaft F of the machine, said eccentrics operating to impart the required reciprocating movement thereto when the shaft is in revolution. Both the vibrating crushing-plate K and its stationary counter-plate H are faced with very hard ribbed steel plates, which can be renewed or replaced at pleasure. These form the upper jaws of the machine into or between which the ore or rock is first fed. p

.A sieve, L, is swung in an inclined position between the frames A A so as to extend from beneath the upper crushing-plates H K in front downward to the rear of the frames, where it terminates over a second set of crushing-plates. These, like the upper set,consist of a stationary coun tor-plate, N, firmlysecured against supporting-cleats between the frames by bolts and nuts, which-allow of its adjustment, and a corresponding vibrating plate, 0, pivoted in front thereof, upon short stout supporting-arms secured to its lower end, and hinged several inches back from thefront face of the plate in a cross-axle, 6, so that when the plate is made to swing upon these arms it obtains a grinding movement in combination with its reciprocating approach to and Withdrawal from the coun ter-plate N. These lower plates, however, instead of having ribbed faces, as have the upper ones, are faced with hard smooth plates, but the opposite surfaces are made respectively convex and concave, as seen in the drawings, to effect a more perfect pulverization of the particles of ore brought be tween them, the faces being set sut'ficiently close to insure this desired result.

The reciprocating movement of the lower vibrating plate 0 upon its hinges is obtained by means of an uprightarm, P, extending from the top or upper edge of the plate to the plane of the driving-shaft F, with which it is connected by a horizontal shackle-bar, R, pivoted upon an eccentric journal upon the center of said shaft.

The upper end of the inclined sieve L is swung to the forward end of the machine, beneath the upper counter-plate, by means of suitable links it, and its lower end is swung to a cross-bar attached to the upright arm P of the lower vibrating plate. The movement of this plate is thus communicated to the sieve, giving it a constant oscillating motion when the machine is in operation.

The shackles M M and R are so pivoted upon the eccentrics of the shaft, and these are so formed thereon, as that the upper and lower jaws or crushing and pulverizing plates are alternately opened and closed; hence, while the upper plate K is crushiu g the ore, the lower plate 0 is released from work, and vice versa.

When the machine is in operation the masses of ore to be crushed are fed in between the jaws of the ribbed crushing-plate K and its torn into small particles and left to drop upon the sieve L below. The lower edges of the'two plates H and K are brought so near one to the other as only to allow the smallest particles to drop through.

The sieve L being in constant oscillation, all the finest particles or grains of the crushed ore are separated from the coarser material and drop through upon the platform below, while the larger fragments are shaken down to the lower jaws N O of the machine, which completes their reduction to a'fine condition.

The movement of the lower plate is similar to that of the upper plate K, although its concave form produces a more continuous rubbing and grinding frictional motion than is found in the upper jaws, and as it is operated by the long upright arm P, the leverage obtained thereby imparts very much greater power to the crushing movements.

Having thus fully described my invention, I claim therein as new and desire to secure by Letters Patent The within-described ore-crushing machine, constructed with two sets of crushing-jaws, and operated by a single intermediate or central shaft, substantially in the manner herein set forth.

M. L. BATTELL.
